SOFTWARE:

DESCRIPTION:
A security issue has been reported in SSH Tectia Server, which can be
exploited by malicious users to bypass certain security restrictions
and potentially to gain escalated privileges.

The security issue is caused due to an error in the handling of
host-based authentication. This may cause a user to be logged on with
wrong credentials to a server running SSH Tectia Server.

Successful exploitation requires that host-based authentication is
enabled and the user must logon from an authorised host.

The security issue has been reported in version 5.0.0 (A, F, and T)
on Windows, Linux and Unix platforms.

SOLUTION:
Update to version 5.0.1:
